sounds like:
update pg_pltemplate
set
tmplhandler='plpython3_call_handler',
tmplinline='plpython3_inline_handler',
tmplvalidator='plpython3_validator',
tmpllibrary='$libdir/plpython3'
where
tmplname='plpythonu';
And that sounds somewhat dangerous to me, especially if I take the comment on
the plpython-python23 page into account: "keeping in mind that this would make
their installation incompatible with most of the rest of the world."
I'd rather not...
Cheers,
Paul
